v2.2.0.1 [Aug 4, 2012]
It contains a lot of UI tweaks, including a complete new display type (see ColorKu mode) and some bug fixes. For visually challenged people the font size of the whole GUI (including all dialogs) can be changed (not applicable under some Linux variants). Interoperability with other sudoku programs has been increased by adding various text file formats for sudokus.
v2.1.3.1 [Nov 5, 2011]
It fixes a bug in the internal caching mechanism that could lead to incorrect steps for Template Set, Template Delete, Brute Force (batch mode only) and Kraken Fish. The display of the selected cells can now be configured to disappear a predefined time after the last selection change.
It includes a rewrite of all internal data structures and solver classes, which makes the solver two to three times faster than version 2.0. The user manual has not been updated yet.
